Anyone want to investigate why this goes wrong?
The following checkin fixed this particular problem: http://svn.zope.org/Acquisition/trunk/src/Acquisition/_Acquisition.c?rev=102564&view=rev The acquisition slice wrapper accepted Py_ssize_t arguments, but then passed these of as C ints (format string 'i'). Changing the format string to 'n' (Py_ssize_t) fixed *this particular case*. Likely more such fixes must be made. In any case, the HTTP range test no longer fails with this fix. -- Martijn Pieters _______________________________________________ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
